Based on a study featuring a representative group of 722 companies, the author presents the various determinants of risk management effectiveness, including behavioural determinants (such as attitude to risk) as well as internal and external determinants (such as human and financial resources and the environment in which the organization operates). Along with a theoretical and practical overview of the various considerations from an international perspective, the reader will gain an insight into the implications for practice. Ultimately, this book formulates conclusions and recommendations for the improvement of tools and systems of enterprise risk management.
